LIQUID-COOLER.

SPECIFICATION forming part of Letters Patent N 0. 668,165, datedFebruary 19, 1901.

Application filed May 31, 1900. Serial No. 18,666- (No model.)

T at whont it may concern:

Be it known that I, WILLIAM COLLIGAN, a citizen of the UnitedStates,residi ng at Waterbury, in the county of New Haven and State ofConnecticut, have invented certain new and useful Improvements inLiquid-Coolers; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to that class of liquid coolers which are designedto hold only a limited amount of liquid which is cooled by means ofcontact with the chilled surfaces of the chambers through which it ismade to pass between the point of inlet and the point of outlet.

The object of my invention is to produce a cooler of the class abovementioned which is more simple in construction than those now in use,more easily taken apart and cleaned, and more cheaply manufactured,having a lengthy liquid course and few parts. I attain this object bymeans of the mechanism illustrated in the accompanying drawings, inWhich Figure 1 is a side elevation of my improved cooler ready for use;Fig. 2, a side elevation of the rod used to connect together the severalparts; Fig. 3, a ground plan of the bottom; Fig. 4, a sectional view ofsame on line a; 00'; Fig. 5, a ground plan of the cover or top; Fig.6, asectional view on line y y, Fig. 5, of the connection-screw used forinlet and outletof the liquid, showing the manner in which it isconnected with the cover or top; Fig. 7, a ground plan of one of thechambersections which constitute the liquid course; Fig. 8, an elevationof the same, and Fig. 9 aperspective view of the washer used between theends of the liquid-course chamber-sections and thetop and bottom.

Similar figures refer to similar parts throughout the several views.

The body of this device is made up of the chamber-sections 1, composedof metal, glass, or any suitable non-corrosive substance, provided withthe projecting shoulders 2 at each end, which are used as bearings forthe washers 3, which are used to prevent leakage between the ends of thechambersections and the top and bottom. For the purpose of decorrosivequalities.

scribing my invention I use four of these chamber-sections, but more maybe used if it is desired to lengthen the liquid course or fewer if itisdesired to shorten it. I do not confine myself to the shape of thesechamber-sections here shown, as the device would work equally well withchamber-sections of a different shape with suitable modifications in theother parts to correspond to the same. The saucer-shaped bottoms (shownby Figs. 3 and 4) are provided with cross-bars or partitions 4c, 5, 6,and 7, so arranged as to receive the ends of the chamber-sections and todivide the inside of the bottom into as many recesses as there arechamber-sections or partitions, a and 6 being partially cut away at 8and 9, respectively, to form passways between the recesses in thebottom. The top or cover (shown in Figs. 1 and in itsinverted-saucer-like form) is similarly provided with crossbars orpartitions 10-, 11, 12, and 13, which in like manner divide the insideof the top into as many recesses as there are chamber-sections. The bar11 is partially cut away to form a passway similar to S and 9.

The top or cover is provided with metal connection-screws 14 and 15, soarranged that the metal of which the top or cover is cast (shown by 16)incloses the flange of the screw and securely holds it, forming apassage (shown by 17) for inlet and outlet purposes in such a Way as toprevent contact with the metal of which the screw is composed. This isdesirable, as the metal of which the screw is composed is chosen with aview only to its being strong and tough, while the metal composing thetop or cover, as well as all the metal or other material which comes incontact with the liquid, is chosen with a view to its non- The metal ofthe top or cover is so cast in and around the connectionscrews thatsuitable holes 17 and 24 are provided for inlet and outlet purposes.

The bottom at 19 and the top or cover at 20 are each suitably depressedat their centers toward their open ends for the purpose of providingconvenient spaces to receive the head 21 and nut 22 of the bolt or rodwhich holds the device together.

The washer above referred to is pierced out at 23 to receive the ends ofthe chamber-sections, the holes 23 corresponding in size to thetransverse sectional shape of the chambersections.

When all the parts are put together and are ready for operation, asshown by Fig. 1, the bar 13 of the cover is directly over (with sectionsintervening) the bar 7 of the bottom. In like manner 10 is over 4, 11over 5, and 12 over 6.

In operation the courseof the liquid is as follows: Introduced into thehole 24 from a supply-pipe suitably connected therewith it flows downinto the chamber of the section directly beneath the inlet 24, thencethrough the passage 8 in the cross-bar 4 of the bottom and up into thechamber between the bars 10 and 11, thence through the passage in thebar 11 of the top and down into the chamber between bars 11 and 12,thence through the passage 9 in the cross-bar 6 of the bottom and upinto the chamber between the bars 12 and 13, thence out through theoutlet 17, to which outlet there may be attached an ordinarydraw-faucet.

If desired, the course may be reversed,using 17 for an inlet and 24 forthe outlet, in which event the positions of the supply-pipe anddraw-faucet are reversed. Ido not wish to confine the location of theinlet and outlet holes to the top or cover, as the same results may beobtained by locating them in the chamber-sections directly beneath theirpresent location, as shown in dotted lines at 25 and 26. I

Having thus fully described my invention, what I claim, and desire tosecure byLetters Patent, is'

1. A liquid-cooler comprising a number of chamber-sections 1 providedwith means for connecting them with the cooperating parts of the cooler;a bottom, the inside of which is provided with a number of recessesequal in number to the number of chamber-sections the partitions betweenwhich recesses are alternately partially cut away to formliquidpassways; a top or cover recessed similarly to the bottom, andhaving a sufficient number of its partitions partially cut away tocomplete the liquid. course, provided with inlet and outlet holes, andmeans for connecting therewith a supply-pipe and draw-faucet; washers 3between the cross-bars or partitions of the top and bottom and theprojecting shoulders 2 of the section-chambers; and means (bolt and nut)for securing together all of the foregoing parts substantially asdescribed.

2. A liquid-cooler comprising a number of chamber-sections 1 providedwith means for connectingthem with the cooperating parts of the cooler,two of said sections being each provided with a hole for inlet andoutlet purposes; a bottom, the inside of which is provided with a numberof recesses equal in numher to the number of chamber-sections, thepartitionsbetween which recesses are alternately partially cutaway toform liquid-passways; a top or cover recessed similarly to the bottom,and having a sutficient number of its partitions partially cut away tocomplete the liquid course; washers 3 between the partitions and theprojecting shoulders 2 of the section-chambers; and means (bolt and nut)for securing together all of the foregoing parts substantially asdescribed.
